15 Claims. 1

This invention relates, in general, to a sacking or bagging device, andone of the objects of the invention is to provide an improved holder forsupporting and holding the sack or bag open to permit filling it.

Another object is to provide in a device of this character, improvedmeans for detachably connecting or securing the mouth of a bag to afilling hopper.

A further object is to provide an improved device of this character,embodying means for holding the bag or sack in an upright position, andwhich means is readily adjustable to accommodat bags of varying sizes.

A still further object is to provide an improved device of thischaracter, which may be readily collapsed or folded into compact formfor storage or transportation.

Still another object is to provide an improved device of this character,which is of a simple and durable construction, cheap to manufacture, andeifective and eiiicient in operation.

To the attainment of these ends and the accomplishment of other new anduseful objects as will appear, the invention consists in the features ofnovelty in substantially the construction, combination and arrangementof the several parts, hereinafter more fully described and claimed, andshown in the accompanying drawings exemplifying this invention, in whichFig. 1 is a perspective view of a bag or sack holder of this character,constructed in accordance with the principles of this invention.

Fig. 2 is a side elevation of Fig. 1, partly in section and partlybroken away.

Fig. 3 is a right-hand end elevation of Fig. 2, with parts omitted andparts broken away.

Fig. 4 is a top plan vew of Fig. 1, with parts omitted.

Fig. 5 is a perspective view of the device, with r the parts nested andin folded relation.

Fig. 6 is a detail sectional view on line 6-6, showing the bag fasteneror securing means in full lines in an inactive position, and in dottedlines in an active position.

The device consists essentially of a base or platform H), which may beof any desired size and construction, and of any suitable material, butwhich is preferably of a rectangular configuration. At one cornerthereof, there is provided a supporting member H, which is hingedlyconnected to the base in any suitable manner, such as by means ofconnecting devices l2, adapting the support H to be positioned to extendacross thebase, as shown in Fig. 1, and to permit it to 55 2 be hingedor turned into an upright position with respect thereto, for a purposeto .be described.

An upright or standard I3 is connected to the support II in any suitablemanner, such as by means of a tubular portion or socket 14, into whichone end of the standard telescopes, and the standard is secured inposition by suitable fastening devices l 5. The supporting member I Iand the tubular or socket member l4 constitute a bracket, the socket 0rtubular portion being arranged at substantially right angles to thesupporting member II. The standard is of any desired height, andpreferably angular in crosssection, and is supported in its uprightposition by means of a clamp or substantially U-shaped member I6 that isconnected to a brace or strut member [1, the forward ends 18 of whichlatter project into bearings l9, secured to the base ID. The brace orstrut passes through the clamp I6, beyond the upright I3, so as to behingedly or pivotally connected to the clamp.

A bolt 20 passes through the sides of the clamp, and the nut or collar2| serves as a means for causing the clamp l 6 to grip and bind theupright l3.

With this construction, and with these parts in the position shown inFig. 1, by loosening the nut or collar 2|, the standard or upright I3may be folded with respect to the base 10, and into the the top andbottom of which are shaped to form diverging flanges 23, 24, to providean intermediate, open, circumferential groove or channel 25.

Secured to the hopper member in any suitable manner, is a bracket 26,which in turn carries a channel-shaped member 21, of a configuration tofit against the upright or standard 13, and which member 21 may be ofany desired length to form a suitable bearing upon and against thestandard. Carried by the member 21, are arms 28 that extend to the rearof the standard, and connected to and supported by thearms, is achannel-shaped member 29 that contacts the rear of the standard andco-operates with the member 27, to clamp the standard therebetween, andthereby support the hopper 22 in any position to which it has beenadjusted upon the standard.

A bearing member 30 is provided, which is preferably of a yokeconfiguration, and is sup ported by the member 29, and through whichyoke the standard I 3 passes, a=thumb screw 3| being also provided,which screw passes through the yoke member and engages a bracket 32 thatis secured to the member 21, and also to the hopper 22. By adjusting thescrew 3| in one direction, the members 21 and 29 may be caused to clampthe standard [3, to hold the hopper 22 in its adjusted position withrespect to the standard, and by loosening the screw, the hopper 22 maybe adjusted or moved lengthwise of the standard. The angularcross-sectional shape of the standard I3 prevents the hopper fromswinging about the standard as an axis.

The flanged upper portion 23 of the hopper may have secured thereto wingmembers 33, to provide an nlargement or guide at the mouth of the hopperto increase the size thereof, and to direct the material into the sackor bag to facilitate filling the latter.

After the hopper has been adjusted upon the standard [3, to the properposition, the mouth or open end of a bag or sack 34 may be securedthereto by sleeving or telescoping such end upon the lower flanged end 2of the hopper, so that the rim of the opening will enter the channel orgroove 25, and may be held in position with respect thereto by means ofa clamping device. A suitable and eificient clamping device embodies asubstantially U-shaped member or bail 35, pivotally supported by oneend, as at 35, upon the hopper 22, on the inside thereof, and which isadapted to be swung about its pivot from the position shown in fulllines in Fig. 6, over the edge of the hopper, into the position shown indotted lines in said figure.

A lever member 31 is pivotally connected, inter- 5 mediate its ends, tothe bail, as at 38, and is preferably provided, on one end, with ahearing or contact element 39, which may, if desired, be in the form ofone or more roller elements. The other end 40 of the lever 3'5 extendsfor any desired distance beyond the pivot 38, and serves as a, meam foroperating or-shifting not only the lever, but also the bail or member35.

With this construction, and when the mouth of the bag is placed over thelower end of the hopper and into the circumferential groove (see Fig. 6)the lever 37 is manipulated to swing th bail over the edge of thehopper, so that the end 39 of the lever may be forced against theoutside of the bag and into the groove or channel 25, to bind the bag tothe hopper.

To collapse or fold the device when the bag is not attached thereto, thelever 31, and bail 35, are folded into the hopper, as shown in Fig. 5.The hopper is then removed from the standard, which may be done byloosening the thumb screw 3!, after which the hopper is placed upon thebase In. The thumb nut 2| is then loosened, and the standard [3 may befolded with respect to the base I0, with the hopper between the base andstandard, as shown in Fig. 5. The thumb nut 2| may then be tightened,and the hopper will be clamped between the standard l3 and the base l0.The standard supporting member H is of a size and configuration topermit of the collapsing and nesting of the parts, as clearly shown inFig. 5.

While the preferred form of the invention has been herein shown anddescribed, it is to be understood that various changes may be made inthe details of construction, and in the combination and arrangement ofthe various parts, with- .in the scope of the claims, without departingfrom the spirit of this invention.
